Description of the invention (1) Scope of the invention Generally speaking, the present invention relates to a fuse shutdown device in a power distribution system used as an overload current protection device. In other words, the fuse cut-off device includes a frame assembly, a pivotable fuse holder assembly incorporated into the seat frame assembly, and a spring member for shifting the fuse holder toward the open-circuit release position. BACKGROUND OF THE INVENTION The main purpose of fuse cut-off devices is to provide protection for power distribution systems and various devices on power lines such as transformers and capacitor banks. The overload current in the system can occur in various situations, such as when animals or trees touch the wires, or more than two wires touch each other. The function of the fuse cut-off device is to cut off the current and cause the fuse holder of the disconnect device to "fall off", thereby preventing the application of an upper voltage to both ends of the fuse holder, and giving visual instructions to the personnel using the line. In the case of shut-off devices from previous processes, the problem was with corrosive environments. In particular, friction caused by the corrosion of the moving parts of the shut-off device can prevent the shut-off device from falling off when the fuse is melted. Therefore, the voltage cannot be removed from both ends of the fuse holder. At the same time, the shutdown device does not fall off, which may cause external flashover. In particular, the shutdown device itself will burn out. This fuse shut-off device does not provide to overcome or reduce the friction caused by the collected corrosion, nor does it ensure that the fuse holder will fall off after the fuse has melted. In addition, shut-off devices from previous processes may not provide the device with protection from damage. Some examples of prior art fuse shut-off devices are disclosed in the following U.S. patents, namely Spurgeon No. 1,939,371; Pittman et al. No. 2,174,476; Evans et al.

Description of the invention (6) One end is attached to the bottom surface (38), one end of the bracket (55) is attached to the upper support member (3 2), and the other end is attached to the hook (54). The two hooks (54) are separated from each other to easily receive the fuse holder (26). The hook (54) is mainly used to connect a load disconnecting tool (not shown), but it can also be used as a guide when the fuse holder (26) is closed. The lower support member (34) has flat top and bottom surfaces (56) and (58), and a central hole is attached to the end (60) of the support member (34) for receiving a fastener (62) such as a bolt. The grip or hinge member (22) is attached to the bottom surface (58) of the lower support member (34) with a fastener (62). The lower support members are also constructed of galvanized or stainless steel. The hinge member (22) contains two symmetrical parts (64), which are joined at the tail end of the wall (66) and open at the front end (68) to form a gap (70), which provides the internal pressure of the trunnion (24) (72) . Each part (64) includes a generally flat top plate (74), a tail plate (76) protruding downward from the rear edge (78) of the top plate (74), and a front plate (80) protruding from the front edge (82) of the top plate (74). ).

As shown in Figures 1 to 3, when the fuse holder (26) is in the closed position, the top portion (170) of its cap (168) is engaged with the upper contact (42). The trunnion (24) is now tied to the first position, and the first pivot point (137) should preferably be below the second pivot point (139) and approximately flush with it in the vertical direction. At the same time, the contact portion (102) of each lower contact (92) of the 'hinge member (22) on the lower contact (92) and the cam portion (122) is applied with a first pressure by the support spring (104) and the trunnion ( 24) The cam portion (122) is engaged, as shown in FIGS. 2 and 7. Printed by the Consumer Cooperatives of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling this page). Under normal circumstances, when the fuse cut-off device is in the closed operating position, current is allowed to pass. Obviously, the current flows from the upper terminal (108) of the mounting bracket (20) through the upper support member (32) to the upper contact (42), and then passes through the cap (168) to the fuse element (16). Then the current may flow through the parallel current path formed by the fuse element (16) to the stud (152) of the trunnion (24), through the cam portion (122) of the trunnion (24) to the lower contact (92), After the cam member (122), the final -15- this paper size fits the national standard (CNS) A4 specification (210X297 Gongchu) '492033 Printed by the Consumer Standards Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs A7 B7 5. The invention description (13) passed Lower terminal (110). When an overload current occurs, the fuse element (16) melts, separating the first and second parts (188) and (190), so that the trunnion (24) and the fuse holder (26) are no longer a fixed body. At the same time, after the first and second parts (186) and (188) are separated, the trunnion (24) can rotate relative to the hinge member (22), and the fuse holder assembly (14) is first lowered to the disconnected position. As shown in Figure 5 and Figure 6. In particular, the trunnion (24) falls to a position corresponding to the fuse holder (26) off position. At this time, the first pivot point (137) should be slightly lower than the second pivot point (139) and be substantially uniform in the horizontal direction. When the trunnion (24) is rotated to its second position at the first pivot point (137), the fuse holder (26) is simultaneously rotated to its open position at the second pivot point (139), so that the cap (168) Separation from the upper contact (42) constitutes a faulty interruption. In addition, the biasing member (118) between the trunnion (24) and the fuse holder (26) provides the fuse holder assembly (14) with a biasing force in the direction of the open position to help it rotate toward the open position. This mechanical force helps to overcome the friction caused by corrupted money, so that the fuse holder assembly (14) is rotated to its open position to interrupt the overload current. In addition, when the trunnion (24) is rotated to its second position, the action of the link catapult (156) forces the fuse element out of the fuse tube (i62) to prevent the shutdown device from being burnt. As shown in FIG. 8, when the trunnion (24) is in its second position: ij: the flat cam surface (134) of the shaft (24) immediately releases both the lower contact (92) and the cam portion (122) Time pressure. Especially when the trunnion (24) is in its first position, the fuse holder (26) is closed as shown in Figure 1, and when rotated to the second position, the fuse holder (26) is opened, as shown in Figure 5. It means that the contact part (102) of the lower contact (92) is moved from the top edge (145) of the contact curve by the first pressure, and the second pressure is -16- This paper size applies to China National Standard (CNS) A4 specifications ( 21〇X297 mm) — „-------- ^ Μψ— (Please read the precautions on the back before filling this page), π 492033 A7 B7___ V. Description of the invention (14) Force contact flat cam surface (134). The second pressure is less than the first pressure because the surface (134) is flat and there is a slight gap between the contact portion (102) and the cam portion (122). Immediately reducing the pressure helps to overcome the corrosion caused Friction, so that the fuse holder assembly (14) is moved to its open position to interrupt the overload current. Once the fuse holder assembly (14) has fallen to the open position, gravity will drop it to the completely off position, as shown in Figure 9 And shown in Figure 10. The trunnion (24) is rotated to the third position, and the second pivot point (139) is now at the first pivot Point (137). At the same time, the fuse holder (26) is rotated to the off position, so that the upper end (164) and the cap (168) point downward. In this way, the fuse element (16) is completely removed from the fuse by the link ejector (156). Seat (26), so as not to damage the fuse cut-off device (10). In addition, the fuse holder assembly (14) is in the off position to indicate that the overload current has been interrupted. Take the fuse holder assembly (14) out of the seat holder assembly (12) It is safe to insert a new fuse element. Then, the fuse block assembly (14) can be installed on the block assembly (12) and closed, so that the fuse cut-off device (10) can be operated again. Printed by the Consumer Standards Cooperative of the Central Bureau of Standards (please read the precautions on the back before filling out this page) When configuring the biasing member or the first biasing member (118) to the fuse holder combination (14), you must determine the fuse cut-off device ( 10) —It will fall off after the overload current occurs, even if the corrosion is sinking, it will overcome the friction caused by the corrosion on the moving part of the device. Especially the flat cam surface (134) of the cam part (122) also provides an explanation Press on Overcome this friction. Or it can increase the pressure exerted by the biasing member or the second biasing member (52) on the upper contact (42) to offset the fuse holder (26) to its open position to help overcome this friction In addition, the corrosion inhibitor can be used to coat the hinge member (22), the trunnion (24), and the upper and lower contacts (42) and (49) to reduce friction. At the same time, it contains corrosion inhibitor-17- this paper Zhang scale is applicable to China National Standard (CNS) A4 specification (210X297 mm j A7
